Don’t get upset with people or situations, both are powerless without your reaction.
We all face various life situations. Exams, relationships, work , family etc, everything tests us and at the end it’s always our response that judges us. We become who we are now with everything we faced and the way we reacted.
A year before, I was a totally different person. We mature not with our age, but with the experience and the lessons. If you now face the situations, that you once faced, you might have a different reaction, maybe you even regret your actions. But you are a collection of everything you said and did, so unless you accept yourself for who you are, you won’t see the beauty of your life.
Just take a moment to think of who you were, a year back and reflect on the moments, good and bad; then you will realize life is way more beautiful with all the changes.
